I've found an old rear engine concrete truck that has a 855 cummins w/auto trans that has the starter on the right side of the engine unlike front engine trucks that are on the left side. Is this a left hand rotation engine Anyone have any interest for use in a bus ? I was told that the transmission, Allison was just rebuild before the truck was parked and the motor ran good ? I'm guessing its from the early 1980's maybe about 250 - 300hp.

They are right handed engine you see the starter on the right side on about all the Cummins generators and industrial engines,if he has the rear tandem drive from the mixer I know a guy with a MCI 7 combo that is looking for one

Its a Tet - Advance Big rears with super singles on pillow blocks and low gearing. The motor and trans are the only parts to use in a bus. I guess the idea of 855's being any good is a matter of opinion, unless you were thinking of 555's or 903's - (pure junk).

If you were a driver back in the day, You had 238 Detroits w/10 spd or 318 w/13 spd, or Cat 1693's or 1674 w/RoadRangers, Mack 237 with twin stick and last but my choice 290 or 350 Cummins. All of the above without power steering. Everyone was tougher and more hard core. If you started driving in a gas job you really beleived 6-71's were fast.

I don't even like Cummins but the 855 was a tough engine smoked a little on start up when you got past that it was ready to roll,and believe it or not I owned a couple of 11 yd Wabco scrapers with the 903 and they never gave any problems but leaked oil at every seam lol

Tom, I had good luck with the 101 Wabco the 10 yard had a 501 Cummins mine were 11 yards level 13 heaped yards with the 903 the engine was under the driver seat you could really see good not like on the 613 Cat I had with the mickey mouse 3208
